Procedure
A solution cyclopropyl-methyl-(3-trimethylsilanylethynyl-benzyl)-amine (Intermediate 90, 0.355 g, 1.38 mmol) in methanol (10 mL) was treated with potassium carbonate (0.13 g, 0.95 mmol) and the resulting reaction mixture was stirred at ambient temperature overnight. The solvent was evaporated in vacuo, the residue was diluted with water and extracted with diethyl ether. The organic phase was washed with brine, dried over anhydrous magnesium sulfate, filtered and evaporated in vacuo to afford the title compound (0.22 g, 86%).
